APPARATUS FOR MANUFACTURING GAS.

SPECIFICATION forming part of Letters Patent No. 392,553, dated November 6, 1888.

Application filed December 17, 1887. Serial No. 259,243. (No model.)

To all whom it may concern.-

Be it known that I, MAGNUs GRoss, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Steam Superheaters for Making Gas; and I do hereby declare .the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the manufacture of illuminating and heating gas in which highlyheated steam is employed.

The object is to produce apparatus for re heating or superheating steam or vapor which shall be of simple and inexpensive construction; which shall be free from exposure to surround i n gs tending to lower temperature; which shall economize heat and conserve the heat of the steam, preventing loss thereof; which shall present the steam to its point of use in the proper condition of heat, and which shall, generally, be highly efficient in use.

\Vith these objeotsin view myinvention resides in a steam-superheater consisting of a chamber to be heated, a vessel or mufile in this chamber closed at one end and open at the other, and containing a pipe to be supplied with steam, and a second chamber formed upon the first, the open end of the vessel or muffle in the first chamber communicating with the second chamber.

The invention consists, furthermore, in the combination, with a casing forming a chamber provided with a heating device and inclosing a gas-retort or gas-retorts, and a vessel or muffle containinga steam-pipe and open at one end, of a mantle, jacket, or hood forming a second chamber against the casing over the open end of the vessel or muffle held therein, the steam-pipe entering the vessel or muffle through the second chamber and passing out of it into the same; and, finally, the invention consists in certain details of construction hereinafter fully set forth and claimed.

The particular construction of the plant for the distribution of the superheated steam-also shown in the drawings in this caseis not herein specifically claimed, since the same forms the subject-matter of another application for patent, one filed of even date herewith and numbered 258, 244.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, Figure l is a front end elevation of the improvement as applied to the furnace with the jacket, mantle, or hood removed. Fig. 2 is a sectional side elevation of the san1e,taken on the line m m of Fig. 1. Fig. 3is asectional end elevation of the improvement, taken on the line 3 y of Fig. 2.

' In the manufacture of gas I prefer to place several benches, A, of any approved construction, into one casing, B, of masonry. Each bench A is here shown provided with the usual furnace, G, for generating heatto heat the gas generating retorts I), of which I place usually six in everybench, so that the entire casing, as shown, contains eighteen. lVithin the easing B is placed a vessel or muffle, E, which is closed at one end and opens at its other end into a chamber, F, formed by ajacket, mantle, or hood, G, held on one end of the casing B, and being of any approved construction. The month-pieces II, secured at one end of the gasgenerating retorts 1), project a short distance through this mantle, jacket, or hood G, as shown in Fig. 2. The steam-inlet pipe I passes through the mantle, jacket, or hood G, and extends into the space F to the open end of the vessel or muffle It. The pipe I here connects with a set of parallel return-pipes or coil of pipe, J, placed inside of the vessel or muifle E, and the other end of the coil passes into the hood and connects with atest-pipe, K, extending downward within the hood, and then out of the same, provided with a cock and serving to test the quality or condition of the steam.

It will be seen that the heat generated in the furnaces Gnot only heats the gas-distilling retorts I), but also the vessel or mul'fleE and the chamber F, so that the steam, after passing through the inlet-pipe I, is not exposed to surroundings of a lowtemperature. As the pipes are located in the highly-heated chamber F, the superheated steam loses none of its units of heat, and is consequently very efficient for generating the gas when mixed with the vapors of hydrocarbons or with suitable gas or vapors from other source and passed through torts D. From the said distributing-pipe also extend downward the superheated-steam-supply pipes O, which furnish the necessary superheated steam for each retort D. The pipes enter through one side of the mouth-pieces H, and then connect with any suitable mixing and injecting apparatus, in the usual manner,

preferably with a mixing and injecting apparatus forming the subject-matter of an application for patent filed of even date herewith and numbered 258,246. An oil-supply pipe, also here shown as connected with the retorts, enters the mouth-piece H outside of the jacket, mantle, or hood G.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A steamsuperheater consisting of a chamber and means for heating the same, a vessel or muffle in this chamber closed at one end and open at the other and containing a pipe to be supplied with steam, and a second chamber formed upon the first, the open end of the vessel or muffle in the first chamber communicating with the second chamber, substantially as described.

2. The combination, with a casing forming achamber provided with a heating device and inclosing a gas-retort or gas-retorts,and a vessel or muflie containing a steam-pipe and open at one end, of a mantle, jacket, or hood forming a second chamber against the casing over the open end of the vesselormuffle held therein, the steam-pipe entering the vessel or muflie through the second chamber and passing out of it into the same, substantially as and for the purpose described.

3. The combination of the casing 13, forming the chamber, with the mantle, jacket, or hood G, forming a second chamber upon the first, the first chamber being provided with a fur-- nace, O, and holding and covering the bodies of retorts D, and containing an open-ended vessel or muffie,E, supplied with a steam-pipe or steampipes, and the second chamber covering or nearly covering the mouth-pieces of the retorts D and the open end of the vessel or muliie Eyand also protecting the steam-inlet pipe and the discharge-pipe and connections, substantially as described.

4. The combination, with the casing B, provided with means for heating it and forming a chamber, and mantle or hood G, forming a second chamber upon this, of the vessel or muiile E, closed in the first chamber,but opening into the second, and containing a steampipe, the inlet and discharge ends of which are in the second chamber, the discharge end being supplied with a test-pipe, N, substantially as set forth.
